abcdidactic uses only technical cookies: the ones it needs to work. None for advertising or analytics, and from third parties only those of Google's button, if you sign in with Google. That is why we ask no permission when you arrive: the Spanish Law 34/2002 (LSSI, art. 22.2) exempts those strictly necessary to provide the service you asked for.
The cookies
| Name | What for | Lifetime |
|---|---|---|
abcdidactic.session_token | Knowing who you are once you have signed in | 1 year |
abcdidactic.session_data | A signed copy of the session, so the database is not read on every request | 5 minutes |
The language needs no cookie: the domain says it (abcdidactic.cat, abcdidactic.es, abcdidactic.com).
The session cookies renew as you use abcdidactic and go when you sign out. All of them stay in your browser and are read only by app.abcdidactic.com.
Signing in with Google
The sign-in page loads Google's button, which may use Google's cookies as Google's policy describes. If you sign in with a code by email, there are no others.
How to remove them
You can delete cookies from your browser's settings. Without the session ones you will have to sign in again.
